var httpPostedFile = HttpContext.Current.Request.Files["UploadedImage"];
if (httpPostedFile != null)
{
// Validate the uploaded image(optional)
// Get the complete file path
var fileSavePath = Path.Combine(HttpContext.Current.Server.MapPath("~/UploadedFiles"), httpPostedFile.FileName);

推荐答案
Asp.net对最大请求长度有限制.你检查了吗?增加参数值
Asp.net has a limit on max request length. Have you checked that? Increase the param value
<system.web>
<httpRuntime maxRequestLength="30096" />
</system.web>
